Cofounder vs Polsia
Two AI cofounders, side by side: which seats each one fills, what it really costs, and who should pick which.
Updated November 11, 2026
Cofounder7.7Full AI cofounder, higher score
The closest rival to a full AI cofounder. The department model is well thought through and the per-company price is simple. The catch is that you also need your own AI coding agent subscription, such as Claude Code or Codex, and the $40 includes only $40 of usage.
Polsia7.3Full AI cofounder
Polsia made the autonomous-company idea famous and does run tasks every night without prompting. It loses ground on cost and trust: its cut of payments and of ad budgets adds up fast once you have revenue, it doesn't do refunds, and reviewers often mention credits spent on fixes.
